英文摘要We report the observation of weak ferromagnetism and possible non-Fermi-liquid behavior in itinerant electronic material Co3SnC via magnetic properties, electrical transport, and specific heat under various magnetic fields. The analysis of magnetic properties suggests that Co3SnC undergoes a noncollinear itinerant ferromagnetic-paramagnetic phase transition around 3.6 K. With this transition, non-Fermi-liquid (NFL) behavior appears at low temperature covering a wide temperature range. The features of NFL are revealed by the power-law temperature dependence of resistivity and also proved by the -TlogT dependence upturn in specific heat and the T-4/3 dependence of inverse susceptibility. With increasing the fields, the temperature coefficient of the T-2 term in the resistivity data shows a (H - H-c)(-0.5) divergence approaching the H-c and reduces monotonously with increasing the field further, apart from the usual 1/(H - H-c) dependence with the whole Fermi surface under the singular scattering. The exponent n in the temperature dependence of resistivity shows an increase from n = 1.0 to 2.0 with increasing the field as the evidence for the field-induced crossover from NFL to FL behavior; it is thought that field dependence of magnetic ground states should be responsible for this crossover; the relative mass enhancement factor lambda(H)/lambda(0) reduces monotonically to nearly 60% at 9.0 T, indicating the gradual suppression of magnetic fluctuations and electron-electron scattering. Our results indicate that Co3SnC is a candidate for exploring itinerant quantum materials.
